  Log:
  Some fairly major changes to this driver.
  
  A) Fibre Channel Target Mode support mostly works
  (SAS/SPI won't be too far behind). I'd say that
  this probably works just about as well as isp(4)
  does right now. Still, it and isp(4) and the whole
  target mode stack need a bit of tightening.
  
  B) The startup sequence has been changed so that
  after all attaches are done, a set of enable functions
  are called. The idea here is that the attaches do
  whatever needs to be done *prior* to a port being
  enabled and the enables do what need to be done for
  enabling stuff for a port after it's been enabled.
  
  This means that we also have events handled by their
  proper handlers as we start up.
  
  C) Conditional code that means that this driver goes
  back all the way to RELENG_4 in terms of support.
  
  D) Quite a lot of little nitty bug fixes- some discovered
  by doing RELENG_4 support. We've been living under Giant
  *waaaayyyyy* too long and it's made some of us (me) sloppy.
  
  E) Some shutdown hook stuff that makes sure we don't blow
  up during a reboot (like by the arrival of a new command
  from an initiator).
  
  There's been some testing and LINT checking, but not as
  complete as would be liked. Regression testing with Fusion
  RAID instances has not been possible. Caveat Emptor.
